Focus on Your Business, Not Your Hammer

You don't need to be a hammer expert as our expertise is on call for you. Built-in features like automatic shut-off protect your equipment from poor operation techniques or the occasional mistake. Internal buffering and integral silencing keeps the noise and power on the job, and out of the cab. If you can run an excavator, you can run a Cat hammer like a pro.

Spend Less Time on Maintenance

Daily greasing is a snap, with one basic point at a convenient height. With the addition of a Cat autolube, the hammer is greased while it runs – not just saving you time, but protecting your investment. Rotate or change the bushing in less than an hour. Gas checks are annual, and quickly accomplished without dismounting the hammer. You can do this yourself… or your Cat dealer can provide comprehensive support on your schedule.

Upgrade to Meet Your Needs

Add a hammer-mounted autolube system to simplify maintenance and improve reliability on more than just a single machine, making it an ideal choice for large production or demolition companies and rental fleets. You can also add a wear package to armor the hammer against harsh working environments in quarries, mines and demolition sites.
